What are some examples of validation controls in software?
Validation controls are mechanisms used to ensure that data entered into a system meets certain criteria. Examples include input masks, required fields, and data type checks.
Can you explain what an input mask is?
An input mask is a set of rules that restricts the format of data entry. For example, a phone number input mask might require users to enter numbers in the format (XXX) XXX-XXXX.
What about required fields? How do they work?
Required fields are inputs that must be filled out before a form can be submitted. They help ensure that essential information is collected.
Are there any other types of validation controls?
Yes, other types include range checks, which ensure values fall within a specified range, and regular expressions for pattern matching.
